Description

technical field

[0001] The invention relates to a waterproof coating for an automobile chassis and a preparation method thereof. Background technique

[0002] Automobile coatings refer to the coatings applied on the body and parts of various vehicles such as cars, and generally refer to coatings and auxiliary materials for new cars and coatings for vehicle repairs. Automotive coatings generally consist of film-forming substances (resins), additives, pigments, and solvents. Intermediate coating for automobiles is also called secondary paste, which is used for coating between automobile primer and topcoat or base coat. It is required that it can not only be firmly attached to the surface of the primer, but also be easily combined with the topcoat on it, playing an important link between the preceding and the following. In addition to requiring good adhesion and bonding with the upper and lower coatings, the intermediate coating should also have good mechanical properties and...
